I bought this a/c to replace my 25 year old that stopped making cold air. I did my research to find a unit that was rated quiet. After installing it and turning on the unit, I was disappointed that it made more noise than the unit it replaced. It just goes to show you, the only way to buy one that is quiet, you must hear it in the store on display. I will live it since now I am 66 yrs. old and it is not so easy for me to remove and install a unit of this size.
Another thing is, Why doesn't it display room temperature as well. I have 2 other smaller a/c units that cost less than half of this one, that has that feature. I don't expect 100% accuracy, but as a guide. BTW they are both over 10 yrs. old and are quiet.
